Protein powder and lectins

What are lectins? 

Lectins are proteins that bind to carbohydrates. They are found in all plants, but raw legumes like beans, peas, peanuts and whole grains like wheat contain the highest amounts.

Are lectins bad for you? 

Lectins have received a lot of bad press in recent years with popular media outlets citing them as a leading cause of obesity, chronic inflammation, and autoimmune disease. Although there may be some truth to these claims, there is very limited research into the long-term health effects of lectin consumption in humans. What we do know about lectins mostly has to do with digestion.

In nature, lectins protect plants against external pathogens such as fungi. The same characteristics that lectins use to defend plants also make them hard to digest; they are stable in acidic environments (i.e. the stomach), and resist being broken down in the gut.

It follows that when consumed, lectins in their active state can cause digestive issues. For instance, eating just a small amount of raw kidney beans can cause bloating, diarrhea, gas nausea, stomach pain, and even vomiting. This is why most legumes are soaked and cooked before eating. Soaking and cooking inactivates lectins, which are water-soluble and typically found on the outside of the plant.

It is important to note that there are different types of lectins, and that different people react to lectins differently. People with digestive diseases like irritable bowel syndrome (IBS), for example, are more likely to experience symptoms after eating lectins. If you have a sensitive stomach, you may therefore want to consider reducing your consumption of lectin-rich foods.

That said, in many large population studies, foods high in lectins like legumes, whole grains, and nuts are associated with weight loss and a decreased risk of chronic diseases like cardiovascular disease and type 2 diabetes. Keeping these foods in your diet is thus probably a good idea. My advice is simply eat them in moderation.


Does protein powder contain lectins? 

Most protein powders do not contain many lectins. That said, to play it safe, I recommend avoiding pea and soy proteins, as peas and soybeans are lectin-rich legumes.

Some people will tell you that you also have to be careful with animal proteins like whey and eggs because many cows and chickens are fed grains and legumes, but this is not true. There may be trace amounts of lectins in animal products, but they are so small that they will not affect your digestion.

To be honest, lectins are not really something that you have to worry about when buying protein powder, even plant-based protein powder. Instead, you should focus on avoiding the many added ingredients known to cause digestive issues.


What is the best lectin-free protein powder?

Because all plants contain lectins, a lectin-free protein powder must be 100% animal-based. This means no plant-based flavors, sweeteners, or additives of any kind. The only protein powders that meet these criteria are single ingredient, animal-based powders like unflavored egg white protein powder and unflavored collagen protein powder.

Having a few lectins in your diet is not a bad thing, however, and is usually a sign that you are eating a healthy, balanced diet. Plus, lectins are by no means the worst thing in protein powder.

Many, if not most, protein powders contain ingredients that can cause painful side effects and long term digestive health problems. Among these ingredients are food additives, dairy-based proteins, and protein concentrates and isolates. 

Avoid food additives

Regularly eating emulsifiers, thickeners, sugar substitutes, and other additives can not only upset your stomach, but also alter the composition of your gut microbiome – the collection of microorganisms living in your gut. This can lead to gut dysbiosis, which is linked to a number of chronic digestive issues. Here is a list of the most common food additives in protein powder:

acacia fiber, acacia gum, acesulfame potassium, artificial flavors, ascorbic acid, aspartame, calcium carbonate, carrageenan, cellulose gum, dextrin, dicalcium phosphate, dipotassium phosphate, erythritol, gellan gum, guar gum, gum arabic, inulin, locust bean gum, maltodextrin, mono- and diglycerides, ‘natural’ flavors, rice bran extract, rice dextrin, rice hulls, rosemary extract, silica, silicon dioxide, sodium alginate, sodium bicarbonate, soluble corn fiber, soy lecithin, sucralose, sunflower lecithin, tocopherols, tricalcium phosphate, xanthan gum, xylitol, zinc oxide

Avoid dairy-based proteins

Dairy-based proteins like whey and casein, although not an issue for everyone, can cause side effects like bloating and diarrhea. This is in part because they contain lactose, a sugar most adults cannot fully digest.

Avoid protein concentrates and isolates

Most protein powders are made from protein concentrates and isolates, which have been mechanically and or chemically stripped of everything but the protein, including the enzymes, fiber, and other natural digestive aids that help you break them down. As a result, they can cause digestive issues and possibly even disruptions to your gut microbiome

Finding a protein powder free from food additives, dairy-based proteins, and protein concentrates and isolates is hard. In fact, 99% of protein supplements contain one or more of these problematic ingredients. This is why we created drink wholesome.
